The supermodel told Regis Philbin and Kelly Ripa that she maintains a healthy lifestyle when it comes to dieting.

“I don’t [diet]. I mean, I do a diet, the diet of my lifestyle,” she said to the talk show hosts this morning. “I guess you call it a diet, but I’ve never done any of those crash diets or all these crazy things that people always write about. I just don’t believe in it. I guess also because of my job I have to be a certain fit. Once I started modeling, I’ve lived a very healthy lifestyle. So I don’t eat very fattening food, and I eat right, I guess.”

Heidi is also getting her kids involved in physical activity with karate.
